Abstract

　This paper presents vector magnetic characteristic analysis of PM motor by using complex E&S modeling taking account of stress effect. It is well known that the magnetic properties of the electrical steel sheets are generally deteriorated due to influence of mechanical stress. However we can reduce iron losses under limited stress conditions in past researches. A low iron losses PM motor designed by taking account of stress effect is presented.
